Low-key: The TV personality carried a bubblegum pink coat over one arm and toted her belongings in a shiny silver backpack

The TV star and her husband, Strictlyprofessional Pasha, 39, announced they were set to become parents for the first time in May.

Revealing the pregnancy news via the Countdown star's Instagram account, Rachel posed in front of a board of letters spelling out the words 'r tiny mate', an anagram of the word 'maternity', while placing her hands on her baby bump.

She captioned the sweet snap: 'Pash and I have a conundrum for you... you have till December to work it out! We're over the moon excited.'

The couple went on to marry in Las Vegas in June, keeping the ceremony 'so secret' that the majority of their friends and family were said to have been completely unaware of the nuptials.

Rachel confirmed the news on social media, sharing shared a picture from their big day, captioned: 'Introducing the new Mr and Mrs Kovalev... We both said yes!'

During a recent appearance on Celebrity Gogglebox, Rachel hinted she could be having a baby girl because she 'couldn't see a penis' in her latest scan.

The mathematician first met Pasha when they were partnered on Strictly Come Dancing in 2013, going official with their romance the following year.

Rachel ended her 16-month marriage to ex-husband James Gilbert weeks after she was eliminated from series, with the split cited as another example of the 'Strictly curse'.

The former couple had been together since they met when they were both studying at the University of Oxford.
